After a few hours of rambling finally I got a working node-visitor. Which recursively visits every required module starting from the definied entry point.

Behind the scenes using node-detective to find all require calls and Node core module to resolve filename. Maybe I will create a package in the future as it gets more mature. In the meantime I have created a simlpe gist demonstrating the core function. Enjoy! ;)

var fs = require('fs');
var path = require('path');
var Module = require('module');
var detective = require('detective');

// node-visitor

function visit(request, parent) {
  var fn;
  try {
    fn = require.resolve(request);
  } catch (err) {
    fn = Module._resolveFilename(request, parent);
  if (!path.existsSync(fn)) {
  var src = fs.readFileSync(fn);
  var requires = detective(src);
  requires.forEach(function(item) {
    visit(item, {
      id: request,
      filename: fn
